WILLIAM WILEY JENKINS, OF LISMAN, KENTUCKY A NUT-LOCK.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed June 26,1907. Serial No. 380,895.

To all whom 'it may concern:

Be it known that 1, WILLIAM WILEY JENKrNs, a citizen of the UnitedStates, residing at Lisman, in the county of Webster and State ofKentucky, have invented certain new and useful Improvements in Nut-Locks; and I do hereby declare .the following to be a lull, clear, andexact description of the invention,'such as will enable others skilledin the art to which it appertains to make and use the same. I

My invention relates to that type of nut-locks in which a plate isarranged to span the bolts and has locking means to engage the sides ofthe nut, and my v engagement with the other nut to engage thespringimprovement resides in a novel construction of springplate adaptedto span and in connection'with a gageplate to lock the-nuts on a pair ofbolts and in the claim appended hereto I will point out the parts andcombination of parts wherein my invention resides in connection with theaccompanying drawing in which,

Figure 1 shows in side view the ends of two joined rails and a pair ofvfish-plate bolts the nuts whereof are locked my improved side lockingspring plate. Fig. 2is a horizontal section of the same taken throughthe locking spring-plate. Fig. 3 shows the nut locking spring-plate.Fig. 4 shows in horizontal section a part of the fish-plate and itsnutted bolts, the nut of one bolt having been partially tightened upon aremovable forked gage-plate and the slotted end of the lockingspring-plate in position to drive the gage-plate from beneath the nutand in doing so to embrace the nut by said slotted end. Fig. 5 is a likeview the spring pushed the gage-platt irom beneath the nut and embracedit and in position to be turned edgewise with the nut a half revolutionto tighten the nut on the bolt and to bring the other end of thespring-plate in plate in locking position as in Figs. 1 and 6. Fig. 6shows the pair of nutted bolts and the spring ,locking plate in positionwhile being turned as the means of tightening one nut in moving to itslocking engagement with the other nut. Fig. 7 shows the slottedgageplate .on which one of the nuts is first partially tightened againstthe fish-plate, and is then removed by the act of engaging the slottedend of the springplate with the nut.

The usual rail-joint fish-plates are secured to the rails by a pair ofbolts 1-1, and for locking the nuts 2,

' on the bolts 1 have designed an improved locking plate 3, preferablyof: spring steel having at one end a slot 4,. open at the end andadapted to receive the shank of the bolt. This slotted end has anoutward upset flange or lip 5-5 at each edge adapted to receive the nutto' form side locks thereto as in Figs. 1-3- and 6. The

other end of the spring-plate has edge flanges or lips 66, upset inwardadapted to receive the other nut -bolt between the upset flanges or lipsof the lockingbeneath the nut as in plate being shown as having by itsslotted end out from beneath and form side locks thereto, so that at itsslotted end the spring-plate is clamped against the fish-plate by thenut, while the other end of the spring-plate is sprung over and by itsupset flanges or lips locks the nut and is maintained in such lockingposition by the spring function of the plate causing it to exertpressure upon the nut or' against the fish-plate, the clamped end ofthe'spring being fixed to the fish-plat; by the nut as in Fig. 2. Whilethe locking function of the plate is made by its reversely upset flangesor lips embracing the nuts, obviously the flanges or lips at the slottedend of the spring-plate renders it impracticable to drive the nut hometo clainp the spring-plate upon the fish-plate because the nut cannot beturned on the plate.

My invention therefore comprises means by which the flanged slotted endof the spring-plate can be engaged with the -bolt and the nut and thenserve as a wrench for turning the nut to tighten it and for this purposeI provide a removable gage-plate 7, about the thickness of thespring-plate and having a slot 8, open at the end adapted with itsslotted end outward to be slid on the fish-plate under the nut over thebolt as in Fig 1. Upon this gage-plate the nut is partially driven homeupon the belt, that is, the nut is not driven tightly upon the gageplate so that it may be pushed out from slotted end of the spring-plateis first set in abutting relation to the slotted end of the gage-plateand by pushing the former forces the gage-plate out from beneath the nutso that the slotted end of the spring lockingplate will then take theplace of the gage-plate and the nut embraced by the side flanges oi thelocking-plate as in Fig. 5. In this position the spring-plate will standaway from the end of and in alinement with the fish-plate so that inturning or thspring-plate around in the direction of the arrow Fig. 6upon the bolt as a pivot the flanges or lips embracing the nut will actas a wrench and cause the nut to be turned, a half revolution therebythe other flanged o'rlipped end of the spring-plate in position to bepulled out from the fish-plate and sprung over the face of the other nutas in Fig. 2. This turning or swing 0 the locking plate effects thetightening of the nut on the bolt on which the plate is turned or swungas a pivot and it is from this pivot point that the spring has itsresilient function to allow the plate to be sprung over and upon thenut; This resilient end of the spring-plate has a hole 9, to .re ceivethe projecting end of the bolt and while thus allowing the spring end ofthe plate to be clamped over the nut, the plate is thereby preventedfrom longitudinal movement which might cause its slotted end to work thenut by the jarring and creeping action of the rails. For this purpose alip 10, may be Fig. 5. For this purpose the upset from the locking-plateso as to engage the nut as in Fig. 2, but the resilient force and thecurved form of the spring-plate caused by springing it over the nut,will constantly tend to hold it in place.

brace and form side locks for the other nut and adaptedto be sprung overand upon its outer face.

2. For railway rail splices, a nut-lock comprising a spring-plateadapted to span the nuts of the splice-bolts and having a slot at oneend open at its end, the said slot being flanked by flanges or lipsupset outwardly, the other end of the spring-plate having flanges orlips upset inwardly at its edges. I

3. For railway rail splices, a nut-lock comprising a spring-piateadapted to span the nuts of the splice-bolts and having a slot at oneend open at its end, the said slot being flanked by flanges or lips,upset outwardly, the other end of the spring-plate having flanges orlips upset inwardly at its edges, and means whereby the slotted end ofthe spring-plate is caused to efiect the clamping action of the nut uponits bolt by rotating the said plate to cause the rotation of said nut todrive it home on the bolt in the operation of locking both nuts.

In testimony whereof I have signed'my name to this specification in thepresence of two subscribing witnesses.
